There had to be 100+ varieties of cookies out there, and what was fun was experimenting with combinations of flavors. I came upon a similar recipe while wanting to use my overripe bananas, and changed a few things, resulting in these sticky cookies that looked like craters on the moon. While the taste profile came out just okay, it was definitely a lessen learned with putting mini marshmallows in with the batter. This was more of a technique failure, for the marshmallows melted quickly as the cookie hardened quickly as well.  

Regardless, I posted the recipe, just in case anyone could offer some advice. Makes 30 cookies.
